I have a glow worm fox icon 18hx showing an f22 fault.

Customer Question

Hi, I have a glow worm fox icon 18hx showing an f22 fault. Having read other people's messages, I can't see the grey knobs or pressure gauge. Plus, the issue is definitely not frozen pipes. There is an inline ball valve under the unit but that's about it. Any. Clues?

If there is no pressure gauge then it will be digital on the display.

Can you not see a silver flexible pipe attached to the copper pipework under the boiler?

If you look underneath on the left hand side, is there a blue knob?
